Overview
Osteoarthritis (OA) of the ankle and/or foot involves degenerative changes in the joint cartilage, leading to pain, stiffness, and functional impairment. 1Diagnosis
Clinical history and physical examination to identify joint pain, swelling, and limited range of motion.
Radiographic imaging (X-rays) to assess joint space narrowing, osteophytes, and subchondral bone changes.
MRI may be used for more detailed assessment of cartilage and soft tissue damage when needed 1.Management
First-line treatments:
- Weight management and physical therapy focusing on strengthening and flexibility exercises.
- Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief.
Adjunctive treatments:
- Intra-articular corticosteroid injections for localized pain relief.
- Orthotics and assistive devices (e.g., ankle braces) to support joint stability and reduce load.
- Hyaluronic acid injections may be considered for some patients 1.Special Populations
Elderly: Emphasis on conservative management with careful consideration of polypharmacy and fall risk reduction strategies 1.
Comorbidities: Tailored treatment plans considering coexisting conditions like cardiovascular disease when prescribing NSAIDs 1.Key Recommendations
Utilize physical therapy and weight management as foundational interventions for improving function and reducing pain in patients with ankle and foot OA (Evidence: Moderate 1).
Consider intra-articular corticosteroid injections for patients with refractory pain, balancing efficacy with potential side effects (Evidence: Moderate 1).
Implement assistive devices and orthotics to enhance mobility and reduce joint stress, particularly in elderly patients (Evidence: Expert opinion 1).References
